Hi all this is the first post of my particular electronic problem. I have a 2012 mk6 2.0 tdi with a display telling me "handbrake on" and chimes when driving and also "oil sensor" which sometimes flashes red telling me "switch off engine". Upon switching the ignition on and with engine off the oil sensor will flash 3 or 4 times and when driving off the handbrake chimes and displays as handbrake on. I have removed the handbrake switch and check it out and its working fine. I have changed the sump oil sensor but with no avail and also main earth wires to battery and bodywork have been cleaned . Strangely both faults began together. I am now at a dead loss and any advice would be well appreciated.
